Data Analysis on the Position of Public Transport Vehicles: A Case Study of Most and Litvínov
Zátka, Josef ; Lysák, Jakub (advisor) ; Svoboda, Jan (referee)
The thesis deals with ex post (i.e. not real time) analysis of data on the position of public transport vehicles. The aim of the work is to design and implement spatio-temporal analyses of this data that will be practically applicable to real public transport networks. Their functionality is verified on data from public transport in the towns of Most and Litvínov, recorded during October 2023. The data is a point record with information about the location of the vehicle, the time and date of recording, the line number, the final stop, the last passed stop, the azimuth and speed of the vehicle movement and its delay. A total of 5 analyses are proposed. The first two analyses deal with the possibilities of effective control of the input data, within them algorithms for positional and attribute control of data are presented. The third analysis monitors and evaluates the spatiotemporal differentiation of delays, focusing on trends in the distribution of delays along the routes of individual lines over time of day and over longer time scales. The fourth analysis looks at the occurrence of delays at individual stops. The final analysis studies the reliability of transfers between public transport links at interchanges. The proposed methods were implemented through scripts written in the Python...

Tool design for production of springs for an organ
Svoboda, Jakub ; Osička, Karel (referee) ; Kalivoda, Milan (advisor)
This thesis focuses on a design for a machined bending fixture to enable the production of valve springs for organs. The reason for choosing this topic was the need to perfect the existing process of making organ springs. The main problem with the original fixture was the poor quality of the spring thread. Valve springs have varying properties and parameters that determine the requirements for the fixture. A 3D model of the complete fixture was created based on the author’s ideas and these requirements. Calculations were then made for a spring of specific dimensions. These calculations showed that the proposed size of the crank is adequate to enable it to be turned by the human hand. A force of 28 N is required at the end of the crank arm to exert the bending torque required to properly thread the spring. This figure is lower than the tabular values for the general European working population. This implies that the crank arm has the designed proportional length. To calculate the same specific spring and verify the function of the fixture, software simulation was also used. When creating the model, in addition to the calculations and simulation, an experiment was also conducted to verify the function and the main idea of the fixture, which is to bend with additional tensile stress. The result of the experiment was a spring that was subsequently compared with a spring produced using the original fixture. The marked difference in the appearance of the thread proved that the author’s idea was correct. The entire fixture and its components are described in detail in the thesis. The comprehensive design of the fixture in the form of a 3D model is prepared for consultation in an organ-making workshop and then for use in production.

Machining technology with the necessity of manual work
Svoboda, Jakub ; Kupčák, Radim (referee) ; Kalivoda, Milan (advisor)
Manual work is still necessary and often irreplaceable. In most cases, it is combined with machine production. As an example of such work we have chosen the production of tin lead alloy organ pipes, which encompasses several machining processes. All aspects of production were analyzed, including specification of the materials used and the various production processes. A pipe was produced according to these specifications for illustration. Individual chapters presented special manual tools and specific machinery. The difficulty and originality of the given production was outlined. This is professional work requiring manual dexterity, logical thought, attention to detail and an artistic spirit. During production we obtained an image showing a part of the cross-section of the pipe perpendicular to its axis. The image shows the correct shape of the soldered joint and the tangential connection of both sides of the sheet. Several aspects of the pipe were evaluated. The final chapters include feedback from customers and a general assessment of this particular work.

System for Recognition of 3D Hand Geometry
Svoboda, Jan ; Mráček, Štěpán (referee) ; Drahanský, Martin (advisor)
V posledním desetiletí došlo ke zvýšení zájmu o užití 3D dat k biometrické identifikaci osob. Možná vůbec největší výzkum proběhl v oblasti 3D rozpoznávání podle obličeje, přičemž je v současné době dostupných vícero komerčních zařízení. V oblastni rozpoznávání podle 3D geometrie ruky byl v minulých letech proveden určitý výzkum jehož výsledkem však nebylo žádné komerční zařízení. Nezávisle na tomto výzkumu se v posledních letech velmi rozšířil trh s cenově dostupnými 3D sensory, což potenciálně umožňuje jejich nasazení v mnoha typech biometrických systémů. Hlavním cílem této práce je vytvořit funkční vzorek bezdotykového systému pro rozpoznávání osob podle 3D geometrie ruky, který bude používat novou levnou kameru RealSense 3D vyvíjenou v současné době firmou Intel. Jedním z problémů při použití RealSense kamery je její velmi malý form factor, který je příčinou nižší kvality výsledných snímků v porovnání s velmi drahými alternativami, které byly použity v již dříve zmíněném výzkumu 3D biometrických systémů. Práce se snaží analyzovat robustnost různých 2D a 3D příznaků a vyzkoušet několik různých přístupů k jejich fúzi. Rovněž je vyhodnocena výkonnost výsledného systému, kde je ukázáno, že navržené řešení dosahuje výsledků porovnatelných se state-of-the-art.
